This release contains a number of small fixes and UI improvements, and two major features:
|
||
|
|
|
||
|
|
* Extended Data Validations
|
||
|
|
* Native Postgres Support
|
||
|
|

|
## Extended Data Validations
|
||
|
|
|
||
|
|
In the [previous release](/3-12-four-new-data-management-features) we provided a feature that allows a SAS developer to create a program (using the source row as input) to determine the values of a particular dropdown.
|
||
|
|
|
||
|
|
This feature has now been extended, to allow the response to contain dropdowns for other cells in the same row. Default values can also be provided for each additional dropdown.
|
||
|
|

|
||
|
|
|
||
|
|
To make this work, the SAS developer simply needs to write a SAS program that takes a source table named `work.source_row` (the row being edited) and creates two output tables:
|
||
|
|
|
||
|
|
* `work.dynamic_values` - the first dropdown
|
||
|
|
* `work.dynamic_extended_values` - the additional dropdowns, and any defaults.
|
||
|
|
|
||
|
|
Your SAS Program (hook script) can be a file on the filesystem (in which case it must end with ".sas") or it can also be a Stored Process or Viya Job in the logical folder tree (metadata or SAS Drive) - in which case it must _not_ end with ".sas". In both cases you should provide the full path and filename in the MPE_VALIDATIONS table.

## Native Postgres Support
|
||
|
|
|
||
|
|
Alongside Redshift and SQL Server we now have native support for Postgres. What does this mean?
|
||
|
|
|
||
|
|
Thanks to SAS/ACCESS engines, we can automatically support a very wide range of database engines. However load times can become significant when the target contains millions (or billions) of rows.
|
||
|
|
|
||
|
|
In order to provide "native" support we update our load process to 'inject' a temporary table using SQL passthrough, which results in significantly faster updates for certain load types, such as SCD2.
